two canoes travel down a river starting at 8:00. one canoe travels twice as fast as the other. after 2.5 hrs the canoes are 5.25 miles apart. find the average rate of each canoe

Solution

average rate = d2 -d1 / t2 -t1

where d2 is the distance at point2 and d1 is distance at point1

average rate = 5.25 / 2.5

average rate = 2.1 miles per hour

average rate of slower canone = 0.84 mile per hr
